Facebook co-founder Eduardo Saverin apparently doesn’t want Uncle Sam in his life any more — after picking up a Harvard degree and making billions of dollars helping Mark Zuckerberg bring the social networking giant to life.

Saverin has renounced his US citizenship and has relocated to Singapore — all apparently to avoid paying any future capital gains taxes on his $4 billion stake in Facebook.

The move came sometime last September but was first widely reported yesterday, just a week before Facebook is expected to start trading publicly.

Saverin’s passport burning differs only by 180 degrees from Zuckerberg’s — who will sell 2 million Facebook shares to pay a reported $1 billion tax bill.

The decision by the Brazilian-born 30-year-old Saverin to thumb his nose at Uncle Sam comes after this country has done so much to make him wildly wealthy.

Saverin owns about 4 percent of Facebook — a company valued at roughly $100 billion.

Once Facebook goes public the company could grow to surpass the gross domestic product of Saverin’s new home Singapore, which has a $200 billion a year economy — and no capital gains tax.

Saverin is living the high life in Singapore and is treated like royalty. He has been investing in tech companies worldwide.

“Eduardo recently found it more practical to become a resident of Singapore since he plans to live there for an indefinite period of time,” a spokesman for the Facebook co-founder told Bloomberg yesterday.

Bloomberg first reported on the citizenship change, which was revealed in an IRS document from April. However, Saverin renounced his citizenship in September.

To renounce citizenship, Saverin would have had to appear at a US embassy or consulate abroad and de-pledge allegiance in front of an official.

The America de-friender first arrived in this country in 1992 and gained citizenship in 1998. Saverin did not return a request for comment yesterday.

Separately, Facebook is testing a product called “Highlight” that would cost everyday users about $2 to ensure their posts reached all of their friends. Typical posts are seen only by about 15 percent of a user’s social network.

The premium post option could unleash a whole new way for Facebook to make money off its 900 million-plus members, but also would change dramatically the history of free usage on the social network.
